The traditional guardrail connection type of formula crane is guardrail plug-in-sleeve with split pin connection, such method, because guardrail and casing are deposited
In fit clearance, guardrail easily shakes, guardrail under Gravitative Loads to opening pin-shaped at shearing force, there are split pin fracture, guardrails
The risk of whereabouts.
Therefore design one kind is connected firmly, and is not easy to shake, extension axis pin service life, safe and reliable connection structure, just
It is inventor to solve the problems, such as.
Utility model content
In view of the deficiencies of the prior art, the purpose of this utility model is to provide a kind of crane maintenance platform guardrail connection knot
Structure can be realized and be connected firmly, be not easy to shake, and axis pin service life, safe and reliable function are extended.
Technical solution adopted by the utility model to solve its technical problems is：A kind of crane maintenance platform guardrail connection
Structure comprising guard rail rod, guardrail wedge, guardrail set, split pin further include the maintenance platform for being connected and fixed guardrail set, the dimension
Guardrail set is connected at equating platform lateral edge, guardrail set both sides side wall top has two through-hole limit holes, institute
It states and is provided with split pin between two limit holes, guardrail set inside is provided with guard rail rod, and one side end face of the guard rail rod connects
It is connected to guardrail wedge, the guardrail, which wedges, to be set below split pin.
Further, guardrail wedge side end face is the triangle to stand upside down, and the guardrail wedge upper end-face edge is parallel with horizontal plane
And left side edge and horizontal plane.
Further, guardrail set side wall is perpendicular to maintenance platform, guardrail set side end face be the triangle of handstand and
Bevel edge angle of inclination is identical as guardrail wedge bevel edge angle of inclination.
Further, the guardrail set upper side, lower end are hatch frame and inner hollow.
Further, the guardrail set width is bigger 1mm than guard rail rod width.
Further, it is fitted closely with guardrail set inner wall under the guardrail wedge assembled state.
The utility model has the beneficial effects that：
1. the design that the utility model the more is pressed the more tight under the action of self-weight by using guardrail in guardrail set, is realized
Guardrail is not easy to shake in the assembled condition, the function of stable connection.
2. the utility model, which by being arranged split pin above guardrail wedge, realizes split pin, which to be only served, prevents guardrail
The effect that back skating goes out, the shearing force that do not conducted oneself with dignity by guardrail, without risk of breakage, safe and reliable function.

Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms also fall within application
The appended claims limited range.
It is that conventional guard rail attachment structure schematic diagram, the utility model guard bar structure schematic diagram, this practicality are new referring to Fig. 1 to 4
Type guardrail covers 4 structural schematic diagrams, the utility model assembling structure schematic diagram comprising guard rail rod 1, guardrail set 4, is opened guardrail wedge 2
Mouth pin 5 further includes the maintenance platform 3 for being connected and fixed guardrail set 4, guardrail set 4, guardrail is connected at 3 lateral edge of maintenance platform
It covers 4 both sides side wall tops and has two through-hole limit holes, split pin 5,4 inside of guardrail set are provided between two limit holes
It is provided with guard rail rod 1,1 one side end face of guard rail rod is connected with guardrail wedge 2, and guardrail wedge 2 is arranged below split pin 5.
2 side end face of guardrail wedge is the triangle to stand upside down, and 2 upper end-face edge of guardrail wedge is parallel with horizontal plane and left side edge and water
Plane is vertical, and guardrail covers 4 side walls perpendicular to maintenance platform 3, and it is the triangle to stand upside down and bevel edge angle of inclination that guardrail, which covers 4 side end faces,
Identical as 2 bevel edge angle of inclination of guardrail wedge, guardrail covers 4 upper ends, lower end is hatch frame and inner hollow, and guardrail covers 4 width
It is bigger 1mm than 1 width of guard rail rod, 4 inner walls are covered with guardrail fit closely under 2 assembled state of guardrail wedge.
When the utility model is used, guardrail is covered the split pin 5 on 4 to pull out, is then aligned with guardrail set 4 by guard rail rod 1
Bottom inject guardrail set 4, be inserted into split pin 5 complete guard rail rod 1 installation because guardrail set 4 outside angle of inclination
Be arranged on guard rail rod 1 the angle of inclination of guardrail wedge 2 it is consistent, under gravity, guard rail rod 1 can be downwards more pressing
Tightly, split pin 5 prevents guard rail rod 1 from sliding outward on top, and not by from the downward shearing force of guard rail rod 1, traditional guardrail connects
In binding structure, with casing there are fit clearance, guardrail easily shakes guardrail, and guardrail forms split pin 5 under Gravitative Loads and shears
Power, the risk to fall there are the fracture of split pin 5, guardrail are opened relative to 1 connection structure of guard rail rod of transmission in the utility model
The service life of mouth pin 5 greatly improves, while also improving the safety coefficient of maintenance platform 3.
The design that the utility model the more is pressed the more tight under the action of self-weight by using guardrail in guardrail set 4, realizes
Guardrail is not easy to shake in the assembled condition, the function of stable connection, by being arranged split pin 5 above guardrail wedge 2, realizes
Split pin 5 only serves the effect for preventing guardrail back skating from going out, and the shearing force that do not conducted oneself with dignity by guardrail safely may be used without risk of breakage
The function of leaning on.
